ragged-right

Arguments:
tab-control

Returns the value of the ragged-right property of its
argument, which must be an instance of the tab-control class.

This property determines whether multiple rows of tabs on a
tab-control may have empty space to the right rather than filling the
width of the tab-control. If nil (the
default), multiple rows of tabs will be made as wide as necessary in
order to fill the width of the tab-control; this choice has a neater
appearance though it can result in some tabs being much wider than
needed to contain their text. If true, multiple
rows of tabs are each only as long as necessary to contain the tab
text with standard margins; this choice may result in an odd
appearance when one row hangs over a shorter row below it.

When all of the tabs fit within a single row, the tabs are never made
wider, since there cannot be a shorter row for a longer one to hang
over.

The ragged-right
property may not be changed on an existing control, and must instead
be specified with the inspector when designing a control (using a
form) or with the :ragged-right initarg of make-instance. (It can be
changed using the inspector when designing a form but not for a
running control, either in the IDE or in an application.)
